Intro

To be honest, I find KZ has been making it a little easy for themselves lately with their wired IEMs. You take a good selling product, put an "X" on the name and sell it again with a new cable and different faceplate colors. Then I write in the description some hair-raising improvements to the predecessor and the new bestseller is ready.

Visually, sonically and technically (for the most part) I have a KZ ZSN PRO in my hands and wonder what exactly the world really needed in the KZ ZSN PRO X.

Handling

Black, blue, gold. Here are the faceplate colors of the ZSN PRO X. The ZSN PRO was "only" available in light and dark gray, with different plastic housing colors. It doesn't really matter, because it's not enough to remarket an IEM. There must be more behind it.
But there is no more difference to the ZSN PRO, except that we get a silver-coated copper cable with the typical KZ limited accessories, which feels better haptically and seems a little more robust.

The ZSN PRO X wears and isolates well and is not the ugliest duckling on the market for my taste.

Sound

Whether it's the X, Y, or Z version of the ZSN PRO, it doesn't change the fact that KZ makes us feel like rubbing a good selling IEM under our noses again, without any significant sonic improvements, which one would look for here, if at all, with a magnifying glass.

I don't want to recite one-to-one the review of the ZSN PRO, but I'll be brief, since almost everything is already written in it.
The bass is for me the most positive sonic characteristic of the ZSN PRO (X), together with the decent stage. It's fun, it's not too exposed, and it has an appealing extension and can handle any genre. It's certainly not a detail monster, but it has good control and that certain something, especially when it comes to quantity.

The mids are reduced in the V-, or actually W-Signaur, and get a slight coloration from the bass. Female voices have more presence, but can also become demanding a bit faster. The mids are not a milestone in the tuning history of KZ, but they are quite okay and appropriate to the price. I don't find them particularly homogeneous or natural, but they are more for showmanship.

The highs have a bite, but unfortunately also a too strong one. They tend to emphasize sibilants and can sometimes be a bit tinny. Nevertheless, I would describe them as very detailed, even if this can sometimes sound a bit artificial. They give some instruments a little more presence than necessary, but that makes them sometimes more exciting than neutrally tuned IEM representatives. Depending on the genre, they can tend to get tired in the long run and the sibilants bother me a bit too much.

i can't really blame the imaging and the stage because the separation works just as well and provides a clear sound image. Together with the bass this is a plus and certainly not too common in the price range.

Outro

Well, my conclusion was to be guessed I think. The ZSN PRO X is neither an upgrade nor a sidegrade to the ZSN PRO. Even though KZ promises a handful of improvements compared to its predecessor, objectively I can hardly detect any. I imagine hearing a bit more brilliance and micro details in the high frequencies and can make out slight technical improvements, which makes up stage and separation, but it's all subtle, if not imaginary. The frequency response doesn't really show any difference and so only the driver characteristics themselves could provide an improvement. The cable is a small upgrade, even though the silver-plated copper cable, unlike its predecessor, emphasizes the highs a bit more, which may not always be beneficial. In addition, the ZSN PRO X is a good 2 dB louder than its predecessor. But that was it. If you are interested in the ZSN PRO (X), you can be happy that the ZSN PRO is now even cheaper and thus represents more and more value.

Legend

Haptic:

Here the processing plays a role and the usability of the scope of supply. Additionally the appearance, wearing comfort and robustness.


Value:
Here I evaluate for me subjectively the price/performance ratio - does not flow into the evaluation!

Z: No Brainer

A: money well spent

B: all right, you can do

C: gives better for less money

D: overpriced

E: collector's price

Daily life:
Here, I focus on the long-term audibility and whether I can hear it well out of the box. This is of course very subjective and therefore only a minimal deduction or bonus.
